简要总结
The goal of this clinical trial is to compare Clear Skin Fomula Supplement to Placebo in healthy men and women ages 18-40 to mitigate mild to moderate non-cystic acne over the course of 12 weeks. Participants will be asked to take a daily supplement, have photos of their face taken and answer questionnaires related to their acne.
详细描述
Non-cystic acne is a common disorder of sebaceous follicles most prevalent among teenagers, has a multifactorial etiology often triggered by the increase in androgen production, and yet, approximately 3% to 8% of adults 25 to 44 years of age continue to have breakouts. The pathogenesis is complex and appears to involve 4 primary features: increased stimulation of sebum gland activity, increased bacterial proliferation (especially Propionibacterium acnes), abnormal follicular hyperkeratinization and resultant obstruction of the sebaceous follicles, and the release of inflammatory mediators. These changes in non-cystic acne patients result in the formation of non-inflammatory and inflammatory lesions including superficial pustules such as comedones (popularly known as "blackheads" or "whiteheads") and papules. The areas most affected by the non-cystic acne include the pilosebaceous follicles of the head and upper trunk, where the sebaceous glands are particularly active.
With the complexity of the pathogenic mechanisms leading to non-cystic acne, consensus guidelines recommend the use of combination therapy including various topical applications (retinoids, antibiotics, salicylic acid, dapsone); oral medications (antibiotics, oral contraceptives, anti-androgen agents, isotretinoin); and numerous other therapies (light therapy, steroid injection, chemical peel, comedone extraction). While the standard treatments for non-cystic acne have varying degrees of effectiveness, significant side-effects including but not limited to skin dryness, irritation, redness, and disturbance of the skin and gut microbiome can occur. Importantly, overprescribing of antibiotics has contributed to antibiotic resistance and reduction of efficacy for these medications.
Use of nutritional supplements as a component of non-cystic acne treatments has increased in popularity due to credible clinical validation and acceptance by the medical community, as well as reported advantages such as better patient tolerance, minimal side-effects, widespread availability and reduced expense versus prescription and over the counter products. Specifically Vitamin A and Carotenoids (the basis of the prescription Isotretinoin), have shown to serve as substitutes when Isotretinoin is inaccessible. Since the progression of non-cystic acne produces free radicals, oxidative stress may be implicated in the origin of non-cystic acne, so that antioxidant vitamins may be valuable adjuncts in non-cystic acne treatment. Additional Vitamins and Minerals have also shown substantial improvement in non-cystic acne.
Although a clinical study has not been previously conducted on VitaMedica® Clear Skin Formula, extensive clinical and patient use data support further investigation. For two decades hundreds of aesthetic and dermatology medical practices in the U.S. have utilized or recommended this VitaMedica® Clear Skin Formula as a safe and effective adjunctive therapy for their non-cystic acne patients. To date, more than 140,000 individual patients have used this dietary supplement in conjunction with their usual treatment regimens.
As the causes of non-cystic acne are multifactorial, and resources to common prescription medications can be costly and frequently ineffective, finding alternative therapies is crucial. Investigators know that diet and nutrition affect all conditions of the skin, gut and brain, so it is logical to infer that vitamins and supplements, while proving successful in treating a multitude of dermatologic conditions, including hair loss, connective tissue disorders, psoriasis and other papulosquamous disorders, could also help mitigate non-cystic acne. Because of this data, two decades ago the VitaMedica® Clear Skin Formula was developed. It includes the following ingredients:

结局指标
主要结局
Percentage/Proportion of subjects who achieve at least a one-grade reduction in the Modified IGA Score
时间窗: Baseline to Day 84
Modified Investigator Global Assessment (IGA) Scale for Non-Cystic Acne The Investigator will use the Modified Investigator Global Assessment (IGA) Scale to assess the severity of a subjects' non-cystic acne. The Modified IGA Scale is a static evaluation of global severity representing clinically meaningful graduations of non-cystic acne. The Modified IGA should be performed prior to the lesion count. The Modified IGA will be performed at visits: Baseline, Day 14, Day 28, Day 56,Day 84 or Early Termination. Subjects are eligible for enrollment if they have facial non-cystic acne with a global severity grade of a 2 (mild) or a 3 (moderate) on the Modified IGA scale at Baseline.
Change in non-inflammatory lesion counts
时间窗: Baseline to Day 84
Open Comedone - (Blackhead) A lesion in which the follicle opening is widely dilated with the contents protruding out onto the surface of the skin, with exposed keratin cells giving the plug a black appearance. Closed Comedone - (Whitehead) A lesion in which the follicle opening is closed, with sebum buildup, which in turn cause the skin around the follicle to thin and become elevated with a white appearance.
Change in inflammatory lesion counts
时间窗: Baseline to Day 84
Papule - A small, solid elevation less than 5 mm in diameter. Most of the lesion is above the surface of the skin. Pustule - A small circumscribed elevation less than 5 mm in diameter that contains yellow-white exudate.
次要结局
- Change in Analysis of the Clear Skin Formula Supplement Subject Satisfaction questionnaire(Day 84/End of Study)
- Change in Non-Cystic Acne Self Assessment questionnaire scores(Baseline to Day 84)
- Change in Non-Cystic Acne Quality of Life questionnaire scores(Baseline to Day 84)
